I created a web page that can help estimate what you should initially set your cold tire-pressures to before starting a trackday session in order to achieve a target tire pressure and temperature:

http://car.dnsalias.com/stp

This estimator requires JavaScript and cookies to be enabled in the browser (only a session cookie is created).

The page has links for the on-line documentation.

This "live-code" estimator is implemented in (browser-side) JavaScript ... so if you're real curious, the code is there. BTW, this also means that, once the page is loaded, there are no more on-line accesses (i.e., so you can load the page into your browser and use it at the track without having an internet connection).

The site creates a session cookie but, other than web-server logs (which go nowhere), creates/tracks/stores no other information.

I threw this together because I was tired of doing the calculations by hand. Hopefully others will find it useful.

If you find issues, let me know and I'll see what can be done about it.
